2.6 CABLE CONNECTIONS
Connection to the mains
The machine is tted with a 3 m long supply voltage cable and plug. Connect the supply
voltage cable to the mains. Should you need to t an alternative plug or mains cable, ensure
installation is completed by an authorised electrician.
NOTE! The fuse size needed is 16 A delayed.
If you use an extension cable, its cross-sectional area should be at least as large as the
machines supply cable (3 x 1.5 mm²). It is recommended to use 3 x 2.5 mm² extension cable.
The maximum length for the extension cable is 100 meters.
The machine can also be used with a generator. The minimum power for the generator is
4.2 kVA, and the recommended power 8.0 kVA in order for the machine to be used at
maximum capacity.
Earth return
The welding circuit earth return cable is already connected to the machine. Clean the
workpiece surface and x the earth return clamp to the work piece in order to create a
welding circuit.
Welding gun
The welding gun is already connected to the machine. The ller wire, shielding gas and
electric current is delivered to the weld inside the welding gun cable. When you press the gun
trigger, shielding gas starts to ow and ller wire feed begins. The arc ignites when the ller
wire touches the work piece. Inside the gun cable there is a factory-installed wire liner that
is best suited for welding with steel and CuSi ller wires. It can temporarily be used also with
stainless steel and aluminium wires. However, this is not recommended because of greater
friction and reduced welding performance, and it may nally lead into failure of ller wire
delivery.
If you mainly use aluminium or stainless steel ller wire, we recommend that you replace the
wire liner with a Kemppi plastic type, which is better suited for the material. For instructions
on how to change the wire liner, please refer to the Maintenance section later in this manual.
The gun neck can be rotated 360° to suit dierent welding positions. The neck is connected via
a standard clockwise screw thread. Always make sure that the neck is almost fully connected
to the bottom thread. This prevents damaging and overheating the neck.
NOTE! If you intend to use other than 0.8 mm diameter steel ller wire, change the welding gun
contact tip, gun liner, and drive roll to match the selected ller wire type and thickness.
